JOHN W. RICHARDSON, OF SOUTH BRAINTREE, MASSACHUSETTS.

MACHINE FOR CUTTING LEATHER.

Specification of Letters Patent No. 30,761, dated November 27, 1860.

To all whom it may concern:

Be it known that I, JOHN W. RICHARDSON, of South Braintree, in thecounty of Norfolk and State of Massachusetts, have invented an ImprovedMachine for Cutting Leather or other Material into Strips, and do herebydeclare that the same is fully described in the following specificationand illustrated in the accompanying drawings, of which' Figure 1 is atop view; Fig. 2, a side elevation; Fig. 3, a front elevation; and Fig.4, a longitudinal section of it.

In the said drawings, A, is the frame or table of the machine, it beingcomposed of two boards, a, 7), arranged at right angles with oneanother, as shown in the figures. The upper board, (1, supports, betweenpar allel ways, 0, c, a movable carriage, B, from the front end of whichtwo bands or ropes, (Z, (Z, extend backward and pass down through thetable and are fastened to a windlass or roller, C, arranged underneaththe part, a, of the table and provided with a ratchet wheel, 0, as seenin the drawings. Furthermore, a sliding frame, D, is applied to thefront side of the part, and extends above and across the table, andsupports a knife E, as shown in all the figures. There is a holding rod,F, placed in front of and parallel to the knife and made to extend overthe movable platform or carriage, B. This rod is bent downward andpasses through the part, a, of the table and on opposite sides of thecarriage. At its two ends, the said rod terminates in two feet, f, f,between which and the part, a, of the table helical springs, g, g, arearranged, each spring being made to envelop the rod and to press itsfeet downward toward and upon two brackets h, h, which extend from thesliding frame, I), as shown in Figs. 2 and 3. The said sliding frame, D,carries a spring pawl G, which works into the ratchet, e. The frame alsohas applied to it, a treadle, H, for depressing it. The springs I, I,are aflixed to bears on the windlass and serves to maintain it inposition during the descent of the knife frame, D, and the retainer orholding rod, F.

In operating with this machine, the piece of leather or other materialto be cut into strips, is to be placed on the top surface of thecarriage, B, and extended underneath the knife, E, and the holding rod,F. Next, if the sliding frame, D, be moved downward by pressure upon itstreadle, the holding rod, F, wi-l-l be depressed by its springs, g, g,and will bear upon the sheet of leather or other material to be cut, theknife being subsequently drawn down through such ma terial after whichthe frame, D, will be raised by its springs. During the elevation of thesaid frame, not only will the holding rod, F, and the knife E, be raisedoff the sheet of leather, but the impelling pawl, G, will be caused toso act upon the teeth of the ratchet as to effect apartial revolution ofthe windlass sufficient to move the carriage and the sheet of leatherthereon, the required distance, preparatory to the knife and the holdingrod being again depressed.

By throwing the pawl out of action with the ratchet, the table may bemoved backward.

I claim My said improved leather cutting machine or arrangement of thewindlass, its ratchet retaining spring, connecting rope or ropes, andimpelling pawl with the table, the carriage, the knife frame, knife andthe holding rod constructed, applied and made to operate together,substantially as and for the purpose specified.

JOHN IV. RICHARDSON.
